Mariah Carey regrets writing a public message apologizing for her shaky performance — “It was kinda pitchy, dawg” — at Michael Jackson’s memorial service last July.

Mariah took the stage at the Staples Center in Los Angeles last summer as the nation came to a standstill to mourn the King of Pop. The songbird sang the Jackson 5 hit “I’ll Be There” — a hit for Mariah in 1991 — during the service, but struggled to hit notes and fought back tears as she performed.

The following day, Mariah took to her Twitter blog to explain that she became overemotional when she saw Jackson’s gold coffin below the stage.

“Trying to sing today was basically impossible for me. I could barely keep myself from crying. I’m sorry that I wasn’t able to pull it together and really do it right, but I was literally choked up when I saw him (Michael) there in front of me,” she wrote at the time.

The singer now wishes she hadn’t spoken publicly about her performance.

“I regret sending that message but I was very emotional and I wasn’t happy with my performance,” the “Obsessed” singer said this week. “But we all did our best to give Michael the send off he deserves. I just forgot the world could read that. I thought I was just talking to my friends. I shouldn’t have done that because that was really only meant for Michael. That was about him.

“It was difficult just to get through the song because I feel as if I have been listening to Michael Jackson’s music my whole life,” Mariah added. When I was a little kid I used to sing all his songs. The whole world suffered a huge loss. The whole world is going to feel this forever. I feel myself blessed to have known him, to have performed with him several times and to have sung at his memorial.”
